Figure 3.nb – Mathematica code used to generate the isoclines shown in Fig. 3.

Demo code for Figures 4 and 5.nb – Example Mathematica code used to generate the equilibria shown in Figs. 4 and 5; to generate the other equilibria, use the appropriate parameter combinations

Figure 6.nb – Mathematica code used to generate Fig. 6 and related figures used in exploring the joint effects of the maximum P recycling rate r and the loss rate s.
